Rda控件（Remote Data Access）能建立多层应用程序，
只需在服务器端安装BDE和一个甚至不用编程的服务软件，
客户端不必Ocx,ActiveX,详细如下：
Works over TCP/IP, making it ideal for creating Internet applications.
No royalty fees for servers.
No need to associated data sets on the server. In fact, there is no need to create any code on the server. Simply place the TDataProvider component on a form and run it and it will automatically handle all requests from clients.
Client-side components are easier to work with since they closely resemble TTable and TQuery instead of TClientDataSet.
It is easy to switch from 2-tier to 3-tier. Simply replace one component with another.
No dependencies on DLLs or ActiveX controls.
